The Best Timber to Use for Your New Deck


What is Timber 

Timber is a natural material derived from trees, typically used for construction and building purposes. It is composed of woody matter and is harvested from various species of trees, including softwoods and hardwoods. Timber is a renewable resource, as trees can be replanted. And it is a common choice for buildings because of its availability, affordability, and strength.


Timber is one of the oldest and most traditional types of material to use for building. And it’s often associated with natural, rustic designs. It is used within structural timber frames and as cladding and joinery, among many other structural and aesthetic applications.


Structural timber frames are the most common way the timber is used in construction. This involves using large wooden beams to form a sturdy frame. Which is then clad in other materials like stone, brick, or metal. These timber frames are often then filled with insulation for further insulation and to improve the thermal performance of the building.


Timber Joinery

Timber joinery is a way of adding detail to a structure and allows for spaces to be separated. Often with decorative frames in a variety of shapes and materials. Timber can have a classic, elegant look and can also be painted to give a contemporary, modern finish.


Also, timber is typically cut from various trees in thicknesses ranging from 5 to 15 cm, depending on the application. Each tree species has unique characteristics and is commonly used for different purposes. For example, softwoods such as pine are used for construction. While hardwoods like oak are a better choice for joinery.


In most cases, timber must be treated and sealed against weather exposure, as it is prone to rotting, warping and cracking. The most popular treatment options include painting, oiling, and varnishing.


Overall, timber is an adaptable and versatile building material that is widely available, robust and cost-effective. It provides a unique aesthetic that is perfect for all kinds of design styles, from the traditional to the contemporary.

Types of Timber for Decks 

Timber is the most traditional material used for decks and is a popular choice due to its classic look and feel. The types of timber used depend on several factors, including strength, weatherproofing, and aesthetics.


Softwoods are often the most economical choice and are widely available. However, they are prone to warping and rotting over time. Common softwood varieties include Redwood, Cedar, and Pine. These woods are best used in more moderate climates and can be pressure treated with a preservative to improve long-term reliability.


Hardwoods are more expensive but provide greater durability and a more attractive finish. Species such as Teak, Ipe, and Meranti are popular and offer excellent strength and resistance to rot, decay, and moisture. Hardwoods are generally more expensive than softwoods, but their heavier construction and impressive visual appeal make them highly sought after for many decks.



1. Cedar vs. Redwood: Cedar has a lower initial cost but may need more frequent treatment and maintenance, whereas Redwood is more expensive but tends to be more durable and longer-lasting.


2. Pressure-treated Pine vs. Composite: Pressure-treated Pine has a lower upfront cost and is more resistant to insects and decay. However, it is not as aesthetically pleasing as composite materials and is not as durable. Composite materials have higher upfront and a longer lifespan, making them more cost-effective in the long run, but they are generally more expensive upfront.


3. Mahogany vs. Ipe: Mahogany is more affordable and widely available, making it a great budget choice, but it is still susceptible to rot and decay, while Ipe is often twice as strong as Mahogany but is comparatively more expensive.


4. Kauri vs. Cypress: Kauri is an excellent choice for outdoor use as it is highly resistant to rot, has a rich colour, and requires only minimal maintenance. But Cypress is still a great choice as it is naturally resistant to insect infestation and will last long.


The best timber for building a deck depends on your budget, style preference and local availability. Many people opt for redwood or cedar, which are both attractive and weather-resistant, with an attractive natural grain and colour. 

Pressure-treated pine is economical but requires regular maintenance and should be treated with a sealer to protect it against the elements. Ipe is another durable, attractive hardwood that is resistant to insects, rot, and mould. 

Mahogany is another strong and visually appealing option, though more expensive than other choices. No matter what type of wood you choose is essential to maintain regular maintenance to prolong the life of your deck.
